摘要
研究无线传感器网络系统中信道链路质量的指示问题。指出了RSSI作为指示量的缺点,通过合理的设计及大量的检测数据,分析验证了平均Corr值对信道链路质量的指示比RSSI值更加有效,同时具有获取时间短的特点,对无线传感器网络功率控制的实现具有参考价值。
In this article channel link quality indication is studied in wireless sensor network system.We pointed out the default of RSSI as indication,then Experimental method is reasonably designed and the massive experimental data are attained,after analyzation we concluded that the average Corr value which can be gained quickly is more effective than the RSSI value in indicating channel link quality,which is valuable in power control of wireless sensor network.
